Abstract

The invention relates to a telemark ski binding having a front jaw (60) that can be fixed to the ski. A front sole holder (66) is disposed on the front jaw (60) in such a way that it cannot pivot in relation to the ski and configured in such a way that it fixes the sole of a ski boot to the ski in the area of the tip of the boot. A support (10, 14) pivotally hinged on a retaining part that can be fixed to the ski in such a way that it can rotate around a pivot pin (2) extending crosswise in relation to the longitudinal direction of the ski and parallel to the top side of the ski is mounted at a location that is staggered backwards in relation to the tip of the boot in the direction of the heel of the boot. A back jaw (20) having a back sole holder (40.1, 40.2, 40.3) is disposed on the support (10, 14) and is configured in such a way as to fix the sole of the boot to the heel of the boot on the support (10, 14). The back sole holder (40.1, 40.2, 40.3) is configured in such a way that it can swing out laterally in relation to the back jaw (20) in order to ensure functioning of a lateral release mechanism of a safety ski binding. Due to the fact that the front sole holder (66) cannot pivot in relation to the ski, good lateral ski control is guaranteed even when the heel of the boot is raised. The lateral safety release mechanism mounted on the back jaw (20) reduces the risk of an injury to the skier in case of a fall.

Description

Telemark ski binding

Technical field

The present invention relates to a ski binding, in particular a binding suitable for telemark skiing (hereinafter referred to as telemark ski binding).

State of the art

When skiing and / or touring in the so-called Telemark style, the heel that can be lifted off the ski (also called the free heel) is not only used for ascending, but also drove down. During the descent, telemark skiing involves cornering with a lunge. To do this, the heel of the shoe must be lifted off the top of the ski on the inside of the curve. In contrast to a ski touring binding of the type described, for example, in WO-A-96/23559 (Fritschi), which bioss is intended for climbing with a free heel, with hardly any significant steering forces being transferred to the ski when climbing, telemark ski bindings must be used (ie ski bindings that are suitable for telemark skiing) even in the position with the heel raised, the ski can still be guided in a controlled manner.

Telemark ski bindings that have been known for decades usually comprise a toe piece permanently attached to a ski with a front sole holder for holding down and laterally fixing the sole of the shoe to the toe, and a cable pulling device provided with tension springs, by means of which the heel of the shoe is essentially resiliently fixed to the toe piece. The heel is left perpendicular to the longitudinal direction of the ski to allow the heel to lift off the ski. When the heel is lifted off, the sole of the Telemark ski shoe is bent in the longitudinal direction, the foremost part of the shoe sole being held down firmly by the sole holder on the top of the ski and also being fixed against lateral displacement. As a result, the skier can still steer the ski even with the heel lifted off via the Telemark ski boot, which is firmly connected to the ski at the front, by transferring steering forces to the ski in the area of the foot and toes. The lateral guidance of the ski boot when the heel is raised is, however, relatively small. In addition, with this type of telemark ski bindings, the cable pulls are worn through relatively frequently due to their heavy use.

US Pat. No. 4,887,833 (Bailey) describes a ski binding which is also suitable, inter alia, for telemark skiing, in which the cable pulling device is replaced by a carrier on which a heel holder designed to fix the ski shoe heel to the carrier is arranged. In the area of the toe, the carrier is pivotably pivoted about a first horizontal transverse axis on a toe piece fastened to the ski and in the ball area it can be bent about a second transverse axis parallel to the first transverse axis. This will make the take off Heel of the shoe with the toe fixed at the same time enables without the need for a cable pulling device like the well-known Telemark bindings. To fix the boot in the binding, on the one hand, the tip of the ski shoe is pressed firmly onto domes attached to the toe piece by means of a fixing bracket, which engage in corresponding holes in the sole of the boot. On the other hand, the ski boot is fixed to the wearer in the heel area by means of the heel holder and additionally by means of a fastening strap that wraps around the boot. These measures firmly attach the boot to the binding and in particular prevent any lateral displacement of the ski boot with respect to the binding (and thus with respect to the ski) in order to ensure good lateral guidance of the ski even when the heel is raised. However, the firm connection between the ski and the ski boot proves to be dangerous in the event of the skier falling, because then uncontrolled forces are transmitted from the skis to the skier's legs and can lead to serious injuries to the skier.

Presentation of the invention

The object of the present invention is to provide a telemark ski binding which, on the one hand, ensures good ski guidance even when the heel of the shoe is lifted off and, on the other hand, reduces the risk of injury to the skier in the event of a fall.

The solution to the problem is the subject of the independent claims.

According to the invention, a telemark ski binding has a front cheek that can be attached to a ski (that is, immovable and non-pivotable) and on which a front sole holder is arranged such that it cannot pivot with respect to the ski. This is designed to fix the sole of a ski boot in the area of the toe of the ski. The ski binding also has a carrier which is pivoted at a point set back from the tip of the shoe in the direction of the heel of the shoe on a holding part which can be fixedly attached to the ski, about an articulated axis running transversely to the longitudinal direction of the ski and parallel to the upper side of the ski, and with a buttock arranged on the carrier a rear sole holder. The latter is designed to fix the sole of the shoe to the heel of the shoe on the wearer. The telemark ski binding according to the invention is characterized in that the rear sole holder is designed so that it can be swung out sideways with respect to the buttock in order to ensure the function of the side draw of a safety ski binding.

The front sole holder is designed in such a way that the sole of a ski shoe inserted into the binding is fixed to or in the area of the toe by the front sole holder with respect to the ski. This means that the sole of the shoe is held down (in a manner known per se) by the front sole holder on the ski (or on a sole layer attached to the top of the ski) and at the same time prevented from lateral displacements and forward displacements with respect to the ski. In order to ensure good lateral ski guidance even when the heel of the shoe is lifted off, however, according to the invention, the front sole holder is arranged on the front jaw in a completely non-pivoting manner, in contrast to the front sole holder of a conventional alpine safety ski binding, which can be swung out sideways to ensure a sideways release with respect to the front jaw.

The rear sole holder is designed such that the sole of the ski shoe inserted into the binding is fixed to the wearer on or in the area of the heel of the shoe by the rear sole holder. That is, the shoe sole is in a manner known per se (as described, for example, in WO-A-96/23559) by the rear sole holder on the carrier (or on a sole pad attached to the carrier, which can be designed as part of the buttock ) held down and at the same time prevented from lateral and rearward displacements with respect to the wearer. In order to ensure the function of the sideways release of a safety ski binding, however, according to the invention, the rear sole holder can be pivoted out laterally with respect to the buttocks, in contrast to the rear sole holder of a conventional alpine safety ski binding that cannot be pivoted out laterally. Due to the safety sideways release in the buttocks, the ski boot is released from the binding in the event of excessive lateral forces between the ski and the ski boot, which can prevent injuries to the skier in the event of a fall. Because the buttock is carried by the carrier with the rear shoe holder, no cable pull is required to hold the shoe heel for the binding according to the invention, which eliminates the disadvantages associated with the cable pulls of previous Telemark ski bindings. The carrier is articulated on the holding part so as to be pivotable about a joint axis running transversely to the longitudinal direction of the ski and parallel to the upper side of the ski. As a result, the heel of a Telemark ski boot included in the binding can be lifted off the top of the ski and pivoted in a plane defined by the longitudinal direction of the ski and the surface normals to the top of the ski. The articulation of the wearer at a point set back from the tip of the shoe in the direction of the heel of the shoe on the one hand and the non-pivoting arrangement of the front sole holder on the toe piece on the other hand ensures that the sole of a Telemark ski shoe, which can be bent in the longitudinal direction, in the area of the foot or toe even with the heel lifted off, it still lies partially on the toe piece or the top of the ski that is firmly attached to the ski. The contact between the sole of the shoe in its foremost region and the toe or the top of the ski enables the power transmission required for steering during telemark skiing from the ball and / or toe region to the ski.

According to a preferred embodiment of the invention, the front sole holder is arranged completely firmly on the toe and is designed as an integral part of the same. In this case, the front jaw and the front sole holder can be formed as a single, one-piece molded part, which enables a particularly simple and stable construction of the front jaw together with the front sole holder. However, it is also possible to arrange the front sole holder to be adjustable in height (e.g. using an adjusting screw) on the toe piece, in order to make it possible to adapt to different sole heights.

The holding part is preferably also formed as an integral part of the toe piece, wherein the toe piece, the front seat part and the holding part can be formed as a single, one-piece molded part. The carrier can be articulated on the same piece of the front jaw on which the front shoe holder is also arranged. This allows the relative position of the carrier Ankenkungsstelle with respect to the position of the Sohienhalter be specified by an appropriate design of the toe. As an alternative to this, the holding part can also be designed as a separate part which is separated from the front cheek that carries the front seat holder. This allows the relative position of the carrier articulation point with respect to the position of the sole holder to be determined during the mounting of the binding on the ski.

According to a preferred embodiment of the invention, the front jaw and the front sole holder are designed and arranged in such a way that they form a receiving space for the tip of the ski shoe that narrows forward at least in one section, in which the tip of the shoe can be pushed forward to insert the ski shoe into the binding . The receiving space is further limited by the toe piece and the front sole holder in such a way that the toe of the ski boot inserted in the binding can only be pushed back out of the receiving area and is immovably fixed in all other directions by the toe piece and / or the sole holder. As a result, the shoe inserted into the binding is well connected in its toe area to the toe and thus to the ski, which is a prerequisite for optimal ski guidance.

The joint axis in the longitudinal direction of the ski is preferably set back by at least 4.0 cm from the toe of the shoe or from the place provided for this in the toe (whereby in connection with the previous description and the patent claims a toe is always to be understood as the foremost place of the corresponding shoe sole) . As a result, the area on which the sole of the shoe rests between the tip of the shoe and the axis of the joint, even when the heel is raised, on the top of the ski or the sole pad on the toe piece is sufficiently large for adequate ski guidance. The joint axis is preferably set back from the toe of the shoe by at least 5.0 cm, in particular even by at least 6.0 cm, in order to enlarge the contact area of the sole of the shoe when the heel is raised and thereby improve the ski guidance. The further the joint axis is set back from the toe, the better the ski guidance is when the heel is off. On the other hand, the heel is lifted off the top of the ski, the more the joint axis from the tip of the boot is set back, because then a greater bending resistance of the shoe sole has to be overcome.

According to a preferred variant of the invention, the carrier is designed as a link chain with a plurality of rigid (i.e. torsionally and torsionally rigid) carrier parts which are connected to one another by means of swivel joints which can each be pivoted about an articulated axis running transversely to the longitudinal direction of the ski and parallel to the top of the ski. This supports the flexing of the flexible sole of a Telemark ski boot. In contrast to conventional telemark bindings with a cable pull, a binding designed in this way has the advantage that it is torsionally and torsionally stiff against corrosion and / or rotational movements about rotational axes that are not parallel to the joint axes of the rotary joints. This improves the steerability of the ski when the heel is lifted off the top of the ski.

As an alternative to forming the carrier as an articulated chain, the carrier or at least part of the carrier can also be made of a flexible material, e.g. be made of an elastic plastic plate to support the flexing of the flexible sole of a Telemark ski boot.

In telemark skiing, the length of the shoe sole changes as a result of the different deflection of the shoe sole as a function of the heel lifting off the top of the ski. Accordingly, the distance between the front and rear sole holder must be changeable to adapt the binding to these shoe sole length changes. According to a preferred embodiment of the invention, this is achieved in that, in the case of a telemark ski binding, with a front jaw which can be fixedly attached to a ski and on which a front sole holder is arranged so as not to be pivotable with respect to the ski, one with respect to the ski by one transverse to the longitudinal direction of the ski and parallel to it Articulated axis of the ski which runs on the top of the ski and a rear jaw arranged on the carrier with a rear sole holder of the rear jaws is displaceably arranged on the carrier in the longitudinal direction of the boot in such a way that it can be displaced against the force of at least one spring in the sense of an increase in the distance between the front and rear jaws, the spring or springs dimensioned in this way and on the Binding are arranged that the holding of the shoe is achieved solely by the spring-caused tension between the toe and the buttock and the binding is free of additional shoe support means. This aspect of the invention also proves to be advantageous in telemark ski bindings without lateral release. The spring or springs are dimensioned and arranged on the binding in such a way that the shoe inserted into the binding is clamped in the binding between the front jaw and the rear jaw with sufficient tension force caused by the spring or springs, even with a minimum shoe length that additional shoe holder means (ie means for fixing the shoe in the binding) would be required. Additional mounting or fastening means (such as shoe fastening straps, clamping devices for clamping the toe, spikes engaging in holes on the sole of the shoe, etc.) can thus be dispensed with entirely, but there is still a play-free shoe holder in the binding and a connection that is sufficiently firm for sufficient ski guidance the ski boot and the binding is ensured. Such additional mounting or fastening means would severely impair or even make impossible the safety function of the sideward draw in a ski binding according to the invention with sideways release.

As an alternative and / or supplement to the longitudinally displaceable arrangement of the rear jaw on the carrier, the carrier itself can also be designed to be adjustable in the longitudinal direction of the carrier, e.g. two carrier parts are connected to one another in a longitudinally displaceable manner and are held together by one or more springs.

In the case of a telemark ski binding according to the embodiment with the butt plate displaceably arranged on the carrier, the spring or the springs for the length adjustment are preferably formed as part of a functional unit which is independent of the carrier and which furthermore can be displaced longitudinally along the carrier and in a desired sliding position on Carrier fixable anchoring element, wherein the spring or springs are arranged such that they act between the buttock and the anchoring element. The anchoring element is used to adjust the distance between the front sole holder and the rear sole holder for different shoe sizes or Shoe sole lengths and essentially determines the longitudinal position of the buttocks on the wearer.

For the length adjustment due to the deflection of the sole, two cylindrical helical compression springs can be provided, which are guided by spring guide means in the longitudinal direction of the carrier, the two helical compression springs being arranged between a rear jaw part and a part of the anchoring element in such a way that they produce a compressive force between the rear jaw and the anchoring element. The spring guide means can comprise two guide rods extending essentially in the longitudinal direction of the carrier, which are fixedly attached to a part of the rear jaw at their front longitudinal ends, while the rear rod ends are guided in a sliding function through bores in a plate-shaped part of the anchoring element arranged transversely to the guide rods , wherein the two helical compression springs are arranged between the buttock section holding the rod ends and the plate-shaped section of the anchoring element which is displaceable in the longitudinal direction with respect to the rods in such a way that they produce a compressive force between the buttock and the anchoring element.

Furthermore, the anchoring element can be provided with a toothing firmly attached to it, which can be snapped into a corresponding toothing fixedly attached to the carrier for fixing the longitudinal position of the anchoring element and can be disengaged from the carrier toothing for moving the anchoring element.

According to a preferred variant of the invention, a first stiff support part is pivotally articulated on the holding part about the joint axis running transversely to the longitudinal direction of the ski and parallel to the top of the ski, and a second stiff support part is pivoted on the first support part about a further joint axis parallel to this joint axis, on which the buttocks is slidably arranged in the longitudinal direction of the shoe. The hinge axis between the holding part and the first support part is preferably set back from the tip of the foot to the heel by approximately 1/8 of the distance between the front and the rear sole holder and the further hinge axis by approximately 1/3 of this distance. The rear jaw is preferably formed by two parallel longitudinal beams which also serve as guide rails of the second carrier part in the longitudinal direction of the shoe, these two longitudinal carriers being connected to one another essentially over their entire length by means of a plurality of cross struts in order to increase the torsional and torsional rigidity of the second carrier part. In this case, the second support part can be designed in the manner of a truss with two rigid parallel supports arranged on the edge, which simultaneously serve as guide rails for guiding the rear jaw, and a multiplicity of connecting struts and / or connecting plates arranged between the parallel supports. The cross struts are preferably designed and arranged in such a way that they can simultaneously be used as gearing on the support side, into which a gearing of this anchoring element can be snapped in order to fix the longitudinal position of an anchoring element according to the embodiment of the invention described above.

Preferably, in a telemark ski binding according to the invention with a spring or springs for length adjustment due to the deflection of the sole and an anchoring element, these springs or springs and the anchoring element are arranged in an essentially closed cavity of the buttock. This protects them from snow and or moisture, so that their function is not impaired by icing. In this case, the carrier can be guided into the cavity in a sliding function through an opening which closely surrounds the carrier in a wall of the buttock delimiting the cavity, so that the buttock is displaceable with respect to the carrier.

The telemark ski binding according to the invention is preferably provided with a ski brake which comprises a braking element and a tread part connected to it in an articulated manner. The kick part can be plate-shaped. The braking element is articulated to a holding part which can be fixedly attached to the ski, this braking element holding part preferably being formed as an integral part of the toe piece. The tread part is designed and integrated in the front jaw so that it holds the braking element up to a non-braking position when a force is exerted on the tread part by the ski boot in the region of the boot tip and is directed downward with respect to the ski. This arrangement ensures that, on the one hand, the ski brake is held up in the non-braking position even when the heel of the shoe is lifted, as long as the tip of the ski shoe points downward Exerts force on the tread part and, on the other hand, functions when the ski boot is separated from the binding in order to brake the ski, even if the ski shoe is separated from the binding in a binding position with the heel of the shoe lifted off.

In order to further improve the safety of holding the braking element in the non-braking position, the tread part can be provided with a locking device which is designed and arranged on the tread part in such a way that it locks the tread part in the position for holding the braking element as long as the ski boot is in relation to the Skis exerts downward force on the step. This ensures that the ski brake does not jump into its braking position until the tread part is completely relieved by the ski boot. In this way, unwanted braking of the ski brake can be prevented.

To support the insertion of the tip of the ski shoe into the front jaws while getting into the binding, the tread part can be provided with one or more rollers on its upper side which can be rotated about horizontal transverse axes. Furthermore, the tread part can be provided with a retaining edge arranged behind the tip of the ski shoe in order to prevent the tip of the ski shoe from being undesirably pushed out of the toe when the heel is raised.

According to a further preferred variant of the invention, the buttock is provided with laterally downwardly projecting supports which, in a binding position with a lowered heel, grip over a correspondingly designed bead firmly attached to the upper side of the ski, in order to prevent the buttocks against lateral displacements with respect to the ski in this position to fix. This can further improve the steerability of the ski in a binding position with the shoe heel lowered.

According to a preferred variant of the invention, the rear seat holder is pivotably arranged on the rear jaw about a substantially vertical central pivot axis fixedly attached to the rear jaw in order to ensure the sideways release. The triggering device for the lateral triggering of the buttock of the telemark ski binding according to the invention can, in particular, be of the type of the sideways triggering device for a toe block described in WO-A-96/23559 be trained. In this variant of the invention, the rear sole holder can have two driver projections projecting downwards on both sides of the central pivot axis, which bear against free end faces of a pressure piece and thereby support the sole holder against swiveling out to the side, the pressure piece being displaceably mounted on the buttocks in the longitudinal direction of the binding and by one in compression spring received in a cavity of the buttocks. Preferably, the cavity receiving the compression spring is arranged in an area below the heel of the shoe, which results in a very compact, weight-saving construction.

To support the sideways release, the buttock can be provided with rollers on the side of the sole holder that can be rotated about vertical axes of rotation. Furthermore, a sliding plate that can be swung out laterally can be provided as a support for the shoe sole in the heel region, in order to ensure sideways release that is essentially independent of the friction of the shoe sole.

In contrast to the previously known telemark ski bindings, in which it is not possible to get into the binding without manually actuating the cable pulling device or the heel holder, the telemark ski binding according to the invention is preferably designed by a corresponding design of the buttock such that a so-called Step-in function is provided so that no binding parts have to be operated by hand to get into the binding. In order to provide a step-in function, the rear sole holder can be pivoted on the buttock, for example in the manner of a conventional automatic heel unit, about a horizontal transverse axis. The automatic heel swivel mechanism for the telemark ski binding according to the invention must allow bioss to get in and out of the binding, because a safety release around the horizontal transverse axis is not necessary for a telemark ski binding with a free heel. Therefore, the automatic heel unit for the telemark ski binding according to the invention can be constructed much more simply than, for example, the automatic heel unit for a customary Aipin ski binding, which must also ensure a safety release around the horizontal transverse axis. The following detailed description of the present invention in conjunction with the accompanying drawings serves only as an example for a better understanding of the invention and is not to be interpreted as a restriction of the scope of the patent claims. Further advantageous embodiments and combinations of features are readily apparent to those skilled in the art from the following description in conjunction with the accompanying drawings and the entirety of the claims, which, however, are still within the scope of the present invention.

Ways of Carrying Out the Invention

The telemark ski binding shown in FIGS. 1 to 7 according to a preferred embodiment of the invention comprises a toe 60, a toe 20 and a carrier connecting the two binding jaws 20, 60 with a first carrier part 10 articulated to the front jaw 60 and a second carrier part 14 carrying the rear jaws 20, the first carrier part 10 being pivotable about a first articulated axis 2 running transversely to the longitudinal direction of the ski and parallel to the top of the ski on the toe piece 60 and the second support part 14 are articulated on the first support part 10 so as to be pivotable about a second joint axis 8 parallel to the first. The binding is designed to hold a ski boot according to standard 75. The binding is also equipped with a ski brake to brake the ski if the Telemark ski binding designed as a safety ski binding is triggered.

In Fig. 1 the Telemark ski binding is shown in a schematic side view. The buttock 20 is in its closing division and the ski brake is shown in its held-up, non-braking position. The outline of a ski boot, which is included in the binding and fixed by it on the ski, together with its sole, is also shown schematically in FIG. 1 with broken lines. 2 shows the binding from FIG. 1 with the same position of the buttock 20 and the ski brake in a schematic plan view from above, and FIG. 3 shows the binding from FIG. 1 with the same position of the buttock 20 and the ski brake in a partial sectioned side view in a position with the heel lifted off the top of the ski. In Fig. 4 the binding of Fig. 1 is shown in a partially sectioned side view. The buttock 20 is still in its closing division, while the ski brake is shown in a lowered, braking position. Fig. 5 shows the buttocks 20 of the binding shown in Figures 1 to 7 in its open position. 6 shows a cross section through the second carrier part 14 of the two-part carrier (10, 14), which connects the rear jaw 20 to the front jaw 60, and FIGS. 7.a and 7.b illustrate the displaceable for the purpose of length adjustment due to the deflection of the sole Arrangement of the rear jaw 20 on the second carrier part 14.

The one-piece toe piece 60 has an essentially plate-shaped base section 62 that can be attached to a ski. At its front end, the upwardly extending and forwardly curved front wall 64 is formed. The front sole holder 66, which has the shape of a bead, is formed on the side of this front wall facing the shoe. In an essentially to In the plane parallel to the top of the ski, the bead-shaped front sole holder 66 has an arcuate plan which corresponds to the average outer shape of a ski shoe tip. The side of the front wall 64 of the toe facing the shoe is formed in a similar manner in an arched manner, its outline corresponding to the average outer shape of the tip of a ski shoe sole according to standard 75.

The base section 62 of the toe piece 60 is provided with a first continuous bore which runs transversely to the longitudinal direction of the ski and parallel to the upper side of the ski. This is designed to receive the first hinge axis 2, to which the first carrier part 10 is articulated. The location of the base section 62 with this bore thus forms a holding part in order to hold the essentially two-part carrier 10, 14 described below on the ski. The first joint axis 2 is offset by approximately 1/8 of the distance between the front 66 and the rear sole holder 40.1, 40.2, 40.3 from the point on the front jaw 60 intended for the foremost sole tip to the heel.

On the base part 62 of the front jaw 60, two lateral support walls 68 are also formed, each of which is provided with a bore for receiving and pivotably mounting a brake element 90 for the ski brake, which is described in more detail below. The two support walls 68 with the bores form a brake element holding part in order to hold the brake element 90 on the ski. The two bores are arranged essentially parallel to the first hinge axis 2 and in alignment with one another and define a first axis of rotation 6, which is essentially parallel to the first hinge axis 2 and about which the brake element 90 is pivotably articulated on the two support walls 68. The two support walls 68 extend laterally on the base part 62 of the front jaw 60 approximately from the position of the first joint axis 2 to the rear.

The first carrier part 10 is substantially U-shaped with two legs 11, 12 and a web 13 connecting the two legs 1, 12. The two legs 11, 12 each have a bore on their leg ends remote from the web 13, which are used for Recording the first hinge axis 2 are formed to articulate the first support member 10 on the front jaw 60. On its jetty side The longitudinal end of the first support part 10 is provided with a bore which is essentially parallel to the two bores in the legs 11, 12 and which is designed to receive a second hinge axis 8 to which the second support part 14 is articulated. The second hinge axis 8 is offset by approximately 1/3 of the distance between the front 66 and the rear sole holder 40.1, 40.2, 40.3 from the point on the front jaw 60 intended for the foremost sole tip to the heel.

A step part 80 for the ski brake is arranged essentially between the two legs 11, 12 of the first carrier part 10 and above the base part 62 of the toe piece 60. The step part 80 of the binding shown in FIGS. 1 to 7 essentially corresponds to the step part 180 shown in FIG. 8, the latter differing from the former merely by an additional locking lever 188. The tread part 80 has an elongated plan and extends forward in the longitudinal direction beyond the position of the front sole holder 66, into the arch formed by the front wall 64 of the toe piece. As a stop for the front edge of the ski boot sole, a wall 82 is formed on the tread part 80 in the vicinity of its front edge, which extends approximately at right angles to the base surface. At the same time, this wall 82 serves to hold the tread part 80 longitudinally displaceable in its curvature in the curvature formed by the front wall 64 of the toe piece 60 and to pivot it about a transverse axis running parallel to the top of the ski, by engaging behind a projection 67 which is correspondingly formed on the toe piece wall 64 .

In the lowered position shown in FIGS. 1 to 3, in which it holds the brake element 90 for the ski brake in a non-braking position, the tread part 80 rests on appropriately designed supports of the sock part 62 of the toe piece 60 and then forms together with the first carrier part 10 a substantially flat contact surface for the ski boot sole in the toe and ball area.

A wall-shaped extension 84, which is angled downward, is formed on the longitudinal end of the base surface of the step part 80, which is near the web 13 of the first support part 10. This extension 84 is at its lower end provided with a through hole which is designed to receive the web 91 of the essentially U-shaped brake element 90 for the ski brake. The bore runs essentially parallel to the two hinge axes 2, 8 on the first carrier part 10 and defines a second axis of rotation 4, around which the brake element is pivotably articulated on the tread part 80.

The brake element 90 is made of a spring steel wire with a circular cross-section and has an essentially U-shaped shape with two legs and the web 91 connecting them, which, as described above, is mounted in the bore in the extension 84 of the step part 80. From the connecting web 91, the two legs on a first section 92, 93 initially run essentially at right angles to the connecting web 91, then on a second section 94, 95 approximately parallel to the connecting web 91 such that the two legs diverge, and then on a third section 96, 97 again roughly parallel to the first section. On its second section 94, 95, the two legs are each passed through one of the bores described above in the two support walls 68 of the base section 62 of the front shoe 60, so as to pivot the brake element 90 on the two support walls 68 about the first axis of rotation 6. The third gates 96, 97 of the two legs serve as actual brake legs 96, 97 of the ski brake, which grip the snow to brake the ski.

In FIG. 4, the movement path of the second swivel joint 4 connecting the tread part 80 to the braking element 90 is shown by a double arrow 9 to clarify the movement sequence. The braking element 90 can be pivoted about the first swivel joint 6, which is fixed with respect to the front shoe 60. As a result, the second swivel joint 4 is moved on a circular path, while the tread part 80 carries out a pivoting movement combined with a longitudinal displacement at its front longitudinal end.

Between the tread part 80 and the braking element 90, a helical spring with two legs is arranged in such a way that it automatically brings the ski brake into the braking position shown in FIG. 4 if the tread part 80 is not held down by the ski boot. In this position, the tread part 80 is lifted upward from the base part 62 and the two legs of the braking element 90 protrude beyond the underside of the ski in order to brake the ski. As soon as the tread 80 through the Ski boot is loaded, it is moved downwards and forwards against the spring force of the coil spring. The second axis of rotation 4 and thus the web 91 of the braking element 90 is moved downward on the circular path shown in FIG. 4 by the double arrow 9, with the pivoting movement of the braking element 90 around the first axis of rotation 6 fixedly arranged on the front shoe 60 protruding legs 96, 97 of the Bremslelementes 90 are pivoted up. A relatively small downward and / or forward force of the ski boot on the tread part 80 is sufficient to hold the tread part 80 down and thus to hold the braking element 90 up.

The second carrier part 14 comprises two parallel longitudinal carriers 15, 16 arranged on the edge in the form of hollow profiles 15, 16, as can be seen in the cross section of FIG. 6. These are connected to one another by means of a plurality of essentially transversely arranged plate and strut-shaped connecting elements (19.1, 19.2, 19.3, 19.4), which together form a connecting plate 17 arranged between the longitudinal beams 15, 16. A part of these cross struts (19.1, 19.2) are designed and arranged in such a way that they form a toothing which is immovably attached to the second carrier part 14 and into which a toothing 21 of this anchoring element 21, 23 can be snapped in order to fix the longitudinal position of an anchoring element 21, 23 described below . A fork-shaped front section 18 is formed on the front longitudinal end of the second carrier part 14. The two fork tips at the front end of the second carrier part 14 are each provided with a bore which is designed to receive the second joint axis 8 in order to articulate the second carrier part 14 on the first carrier part 10. At its longitudinal end opposite the fork-shaped front section 18, the second carrier part 14 carries the rear jaw 20, the two longitudinal carriers 15, 16 simultaneously serving as guide rails 15, 16 for guiding the rear jaw 20.

The rear jaw 20 has an L-shaped base part, one leg 22 of which is arranged essentially in the longitudinal direction of the carrier part 14, while the other leg 24 is arranged essentially perpendicularly thereto. The leg 22 arranged in the longitudinal direction of the carrier has an essentially closed cavity, which is penetrated by the second carrier part 14 in the longitudinal direction in a sliding guide around the rear jaw 20 in the longitudinal direction to be slidably connected to the second carrier part 14. In order on the one hand to provide a length adjustment due to the deflection of the sole and on the other hand to create a possibility of dividing the binding for different shoe sizes or shoe sole lengths, a functional unit for changing the distance between the front sole holder 66 and the rear sole holder 40.1 is independent of the carrier part 14 in this cavity. 40.2, 40.3 arranged.

The functional unit for changing the distance between the front and the rear sole holder comprises an anchoring element 21, 23 which is displaceable in the longitudinal direction along the carrier part 14 and can be fixed in a desired sliding position on the carrier part 14. The anchoring element 21, 23 comprises a spring steel sheet 21 which extends in the longitudinal direction of the carrier. which is provided with a toothing, and a plate-shaped part 23 arranged transversely to the longitudinal direction of the carrier. The toothing of the spring steel sheet 21 can be snapped into the toothing on the carrier part 14 formed from the cross struts 19.1, 19.2 in order to fix the anchoring element 21, 23 with respect to the carrier part 14 . By means of an actuating lever 25, the spring steel plate 21 having the toothing can be raised and thus the toothing of the anchoring element 21, 23 can be disengaged from the toothing on the carrier side, whereupon the anchoring element 21, 23 can be displaced in the longitudinal direction along the carrier part 14 and then by latching the toothing in one desired shift position can be fixed again. In this way, the distance between the front sole holder 66 and the rear sole holder 40.1, 40.2, 40.3 can be adjusted in order to adjust the binding for different shoe sole lengths.

The rear jaw 320 shown in FIGS. 10 and 11 is provided with a functional unit identical to that shown in FIGS. 1-7 for changing the distance between the front and rear sole holder, with corresponding anchoring elements 321, 323, actuating lever 325 and helical compression spring 329.1. In contrast to the representations in FIGS. 1-7, the functional unit is shown in FIGS. 10 and 11 in a position with the actuating lever 325 raised, in which the toothing of the anchoring element 21, 23 is disengaged from the toothing on the carrier side. For the length adjustment of the binding as a result of the deflection of the sole, the functional unit further comprises a spring mechanism with spring guide means in the form of two guide rods 27.1, 27.2 which extend essentially in the longitudinal direction of the carrier and which are each fixedly attached to a part of the horizontal leg 22 of the buttock 20 at their front longitudinal ends . The rear rod ends are guided in a sliding function through bores in the plate-shaped part of the anchoring element 21, 23 arranged transversely to the guide rods 27.1, 27.2. A cylindrical helical compression spring 29.1, 29.2 is arranged on each of the two guide rods 27.1, 27.2 in such a way that they produce a compressive force between the part of the buttock leg 22 holding the guide rods and the plate-shaped part 23 of the anchoring element. (For the sake of clarity, the helical compression springs 29.1, 29.2 are only indicated at their longitudinal ends in FIGS. 7.a and 7.b). In the embodiment of the invention shown in FIGS. 1 to 7, the rear jaw 20 is displaceable in this way by up to 75 mm in the longitudinal direction with respect to the second carrier part 14 in order to adjust the distance between the front sole holder 66 and the rear sole holder 40.1, 40.2 , 40.3 to ensure a change in the length of the shoe sole due to the deflection of the shoe sole.

A jaw structure part 30 is arranged on the other leg 24 of the rear jaw base part, which leg 24 protrudes from the second carrier part 14. The rear shoe holder 40.1, 40.2, 40.3 is molded onto the side of the shoe structural part 30 facing the shoe. The rear holder 40.1, 40.2, 40.3 has the shape of a bead. In the binding position with the heel of the shoe lowered, it has an arcuate plan in a plane essentially parallel to the top of the ski, which corresponds to the average external shape of a heel of a ski shoe. The side of the shoe structure part 30 facing the shoe is curved in an analogous manner. In the illustration in FIG. 5, the hatched areas each represent a section through the longitudinal center of the rear shoe, where the arch shape of the rear sole holder 40.2 and the side of the shoe structural part 30 facing the shoe extends furthest to the rear. The outline shape of this side and of the rear sole holder 40.3 is also drawn in solid lines on one side edge, where they extend the most forward due to the arc shape. The buttock 20 is also shown in an analogous manner in FIG. 4. The cheek structural part 30 is mounted so that it can be swung out laterally about a central swivel axis 32 on the upstanding leg 24 of the base part of the buttock 20, the cheek structural part 30 being held in its desired swivel position on the cheek base part by a flexible triggering device for fixing the ski shoe to provide a lateral security release of the ski binding. The release device corresponds essentially to the side release device on the front jaw of a ski touring binding of the type described in WO-A-96/23559 (Fritschi).

To support the sideways release, a roller 48, which is rotatable about a vertical axis of rotation, is arranged on both sides of the rear jaw, below the side edges of the rear sole holder 40.1, 40.2, 40.3. Furthermore, a laterally pivotable sliding plate 46 is also arranged in a manner known per se as a support for the shoe sole in the heel region on the leg 22 of the buttock base part arranged on the second carrier part 14, in order to ensure a sideways release which is essentially independent of the friction of the shoe sole.

In order to create a shoe guiding device which guides the rear edge of the shoe sole around the rear sole holder 40.1, 40.2, 40.3 when entering and exiting the binding, a one-piece rocker around a substantially horizontal transverse axis 52 is further on the structural part 30 of the buttock 20 articulated. The rocker comprises two guide arms 54, 56 arranged approximately parallel to one another and perpendicular to the transverse axis 52, and an actuating arm 58 which extends from the transverse axis 52 essentially in the opposite direction with respect to the guide arms 54, 56.

The transverse axis 52 is arranged at approximately the same height on the structural part 30 of the rear jaw 20 as the bead-shaped rear sole holder 40.1, 40.2, 40.3 with respect to the second carrier part. This minimizes the length of the guide arms 54, 56 which is required to guide the shoe sole in a circular path around the rear sole holder 40.1, 40.2, 40.3. The guide arms 54, 56 extend from the transverse axis 52 through two slot-shaped passages 34, 36 in the structural part 30 and in the rear sole holder 40.1, 40.2, 40.3, which are each eccentrically formed between the center and the side edges in the structural part 30 and in the longitudinal direction run. The bead-shaped rear sole holder 40.1, 40.2, 40.3 is divided into three parts by the two slot-shaped passages 34, 36. The length of the guide arms 54, 56 is dimensioned such that they protrude in the vicinity of the rear sole holder 40.1, 40.2, 40.3 through the slot-shaped passages 34, 36 and in each case beyond the shoe-side edge of the rear sole holder 40.1, 40.2, 40.3. As a result, when entering and exiting the binding, the sole projection on the heel-side longitudinal end of the shoe is guided by the two guide arms 54, 56 essentially in a circular path with the transverse axis 52 as the center around the rear sole holder 40.1, 40.2, 40.3, the two guide arms 54, 56 touch the sole of the shoe off-center.

In the sides of the two guide arms 54, 56 pointing towards the shoe sole, an angular recess 57 is formed in each case in order to receive the lower edge of the shoe sole. As a result, when entering and exiting the binding, when the guide arms 54, 56 touch the shoe sole, the latter is held on two sides of the lower edge by the guide arms 54, 56 in order to ensure secure guidance of the shoe sole.

A cylindrical helical spring 44 with two legs is arranged above the transverse axis 52 in the two slot-shaped passages 34, 36. By supporting one leg on the cheek structural part 30 and the other on a stud 45 on both springs 44, which is attached to a side surface of the guide arm 54, 56 extending through the slot-shaped passage 34, 36, the two springs 44 act between the jaw structural part 30 and the rocker. The spring legs supported on the knobs 45 can slide freely on them and the springs 44 and the knobs 45 are arranged with respect to the transverse axis 52 in such a way that their lines of action in a first swivel position of the rocker on one side and in a second swivel position on the other Run past the transverse axis 52. This arrangement creates a bistable tilting device for the seesaw to move the seesaw in the manner of a to switch mechanical flip-flops between two stable pivot positions on the transverse axis 52 back and forth. When the rocker is actuated from one stable to the other swivel position, it is moved over a dead center in which the lines of action of the springs 44 run through the transverse axis 52.

The first stable pivot position of the rocker shown in FIG. 5 defines the open position of the rear binding jaw 20 or the binding. In the open position, the two guide arms 54, 56 are directed upward and the actuating arm 58 is directed downward. In this position, the heel of the shoe can be placed on the guide arms 54, 56 and then pressed down to get into the binding without manual manipulation being necessary. This provides a so-called step-in function.

The second stable pivoting position of the rocker shown in FIGS. 1, 2, 3 and 4 defines the closing division of the rear binding jaw 20 or the binding. In the closing division, the two guide arms 54, 56 are directed downward and the actuating arm 58 is directed upward. In this position, the shoe sole held on the second carrier part 14 by the rear sole holder 40.1, 40.2, 40.3 is not touched by either of the two guide arms 54, 56. This ensures that in the closing division, the guide arms 54, 56 do not hinder the holding function of the rear sole holder 40.1, 40.2, 40.3 or the safety function of the sideways release device.

On the leg 22 of the buttock base part arranged on the second carrier part 14, a wall-shaped, downwardly projecting support 26 is formed on each of the two longitudinal sides, which in a binding position with a lowered heel engage over a correspondingly designed longitudinal bead 28 firmly attached to the top of the ski. As a result, the buttocks 20 are fixed against lateral displacements in the binding position with the heel lowered, whereby the steerability of the ski in this binding position is further improved.

3 shows the binding of the heel raised from the top of the ski. From this illustration it can be clearly seen how the heel part 62 of the toe piece 60, the step part 80, the first carrier part 10 and the like when the heel is lifted off second support part 14 a support for the ski boot sole is created which, due to the pivotability of the two swivel joints 2, 8 between the first support part 10 and the toe 60 on the one hand and the first support part 10 and the second support part 14 on the other hand, is essentially curved in the longitudinal direction, to support the longitudinal deflection of the sole of a Telemark ski boot.

To get into the binding, if necessary, it is first brought into its open position by pressing the actuating arm 58 down either by hand or by means of a ski stick. The toe is then inserted into the toe 60 by sliding the sole protrusion on the toe under the front sole holder 66 on the toe 60. As a result, the tread part 80 on the toe piece 60 is pressed down and the ski brake is thus raised. The shoe heel is then placed on the guide arms 54, 56 on the buttock 20 in such a way that the lower edge of the shoe sole is received in the guide arms 54, 56 by the two angles 57. Now the shoe heel is pressed down, whereby it is guided by the guide arms 54, 56. When the shoe heel is pressed down, the buttocks 20 are first displaced backwards, away from the shoe by the two guide arms 54, 56 against the force of the compression springs 29.1, 29.2, until the two guide arms 54, 56 run essentially parallel to the second carrier part 14. When the heel of the shoe is pressed down further, the base 20 of the buttock 20 is pressed forward again towards the shoe by the compression springs 29.1, 29.2, the rear sole holder 40.1, 40.2, 40.3 being pushed over the heel-side protrusion of the sole of the shoe. After the shoe heel is lowered to the second carrier part 14 or the base part of the buttock 20 and the shoe is thus completely inserted in the binding, the rocker is moved a little further in the direction of entry by the two coil springs 44 of the tilting device until the Closing division of the binding is reached, in which the shoe sole is no longer touched by guide arms 54, 56.

To exit the binding, the actuating arm 58 is pressed down, for example by means of a ski pole. As a result, the two guide arms 54, 56 are first moved forward and upward in such a way that the two angles 57 of the Guide arms 54, 56 embrace the lower edge of the shoe sole. By pressing the actuating arm 58 further down, the heel-side shoe sole projection is moved forward and upward in order to guide it around the rear sole holder 40.1, 40.2, 40.3. Since the toe is held immovably by the toe 60, the butt 20 is simultaneously displaced backwards by the two guide arms 54, 56 against the force of the compression springs 29.1, 29.2 in the longitudinal direction, until the two guide arms 54, 56 in run substantially parallel to the second support part. Subsequently, when the heel is raised further, the two guide arms 54, 56 are pivoted further upward and the buttocks 20 are pressed forward again towards the shoe by the compression springs in its base part until the binding is in the open position. In the open position, the rocker is held in place by the two coil springs 44 of the tilting device in the pivoting position with guide arms 54, 56 pointing upward, so that manual manipulation is not required for subsequent entry into the binding and the step-in function is thus ensured . After the toe of the toe 60 has been removed, the ski brake is automatically brought into its braking position by the helical spring in the ski brake.

8 shows a detail of a step part 180 together with a locking device 188 for a telemark ski binding in accordance with a further preferred embodiment of the invention. So that to hold down the

Tread part 180 required force, which is to be exerted by the ski boot on the tread part 180, can be further reduced in the embodiment shown in FIG

Invention on the foot part 180, a rocker-shaped locking lever 188 articulated on the base of the foot part 180. One arm of the locking lever 188 is as

Locking hooks formed while the other arm of the seesaw-shaped

Locking lever 188 serves as an operating arm. Is in the lowered position of the

Trittteiis 180 the actuating arm of the locking lever 188 by the

The sole of the ski boot is loaded, so the locking hook is hooked around a cam formed on the base of the toe piece. As a result, even with an extremely low force on the tread part 180 or the actuating arm of the locking lever 188, any lowering of the Prevents braking element, which could lead to unwanted braking of the ski.

9 shows a front jaw 260 for a telemark ski binding in accordance with a further preferred embodiment of the invention, which differs from the front jaw 60 of the binding shown in FIGS. 1-7 essentially by a differently designed ski brake. 9 shows the front jaw 260 with the ski brake in a lowered, braking position, the part of the front jaw 260 carrying the sole holder having broken away for the sake of clarity.

The ski brake of the front jaw 260 comprises an essentially plate-shaped tread part 280, which is articulated at its rear longitudinal end about a horizontal transverse axis 205 on a base part 262 of the front jaw 260. At its front longitudinal end, the tread part 280 is provided with an essentially horizontal transverse slot opening which is open to the front. The connecting web of an essentially U-shaped braking element, which in addition to the connecting web further comprises two legs 296 connected to one another, the latter serving as the actual brake legs, is accommodated in this in the longitudinal direction and pivotable about a horizontal transverse axis. The brake legs 296 are pivoted about a horizontal transverse axis 206 on the base part 262 of the front shoe 260, the transverse axis 206, on which the brake legs 296 are hinged, being arranged in front of the transverse axis 205, on which the tread part 280 is hinged.

When a ski boot is inserted into the front jaws 260, it presses the kick part 280 down with the tip of the sohi. As a result, the brake element in its front part is pivoted downward about the transverse axis 206, as a result of which the brake legs 296 are pivoted upward about the transverse axis 206 into a non-braking position.

To support the insertion of the tip of the ski shoe into the front jaws 260 while getting into the binding, the tread part is provided with a plurality of rollers 201, 203 which can be rotated about horizontal transverse axes and which are on the top of the tread part 280 project. When the ski shoe is inserted into the front jaws 260, the front of the ski shoe sole rolls practically smoothly over these rollers 201, 203. Furthermore, the tread part is provided with a retaining edge 207 arranged behind the tip of the ski shoe, which prevents the tip of the ski shoe from being undesirably pushed out of the front jaw 260 when the shoe is raised Shoe heel prevented.

A rear jaw 320 for a telemark ski binding according to a further preferred embodiment of the invention is shown in FIGS. 10 and 11 in a representation corresponding essentially to FIG. 5, the rear jaw 320 in FIG. 10 in its closing division and in FIG. 11 is shown in its open division. The buttocks 320 shown in FIGS. 10 and 11 essentially differ from the buttocks 20 shown in FIGS. 1-7 only in another design of the mechanism for getting in and out.

A rear jaw intermediate part 331 is mounted on a leg 324 of the L-shaped base part of the rear jaw 320, which protrudes from the second carrier part and is pivotable about a central pivot axis 332. A rear-jaw structural part 330 is pivotably connected to the rear-jaw intermediate part 331 about a horizontal transverse axis 352. The rear cheek structural part 330 is designed in the manner of a two-armed rocker, with a bulged rear seat holder 340 being formed on the front rocker arm. Analogous to the embodiment shown in FIGS. 1-7, the rear jaw 320 shown in FIGS. 10 and 11 is also provided with rollers 348 which can be rotated about vertical axes of rotation to support the lateral release. The rear rocker arm 358 serves to actuate the rear cheek structural part 330, in that the rear cheek structural part 330 is pivoted about the pivot axis 352 by means of the actuating arm 358 in the manner of a heel automat known for Aipin ski bindings in order to get in and out.

A pressure piston is received in a bore of the rear jaw structural part 330 and is pressed by a compression spring onto a pressure surface formed on the rear jaw intermediate part 331. The pressure surface is designed in such a way that when pivoting the buttock structural part 330 about the pivot axis 352, the pressure piston and thus the buttock structural part 330 in two through the pressure surface predetermined latching positions engage, which define the closing division or the open position of the binding.

In contrast to a customary Aipin ski binding, the tread mark shown in FIGS. 10 and 11 does not require a step on which the heel of the shoe would have to be placed to get into the binding in order to then press the automatic heel down. In the telemark ski binding shown in FIGS. 10 and 11, the distance between the front sole holder and the rear sole holder 340 is set such that the shoe heel rests on the rollers 348 after inserting the toe of the shoe in the toe pieces. After placing the shoe heel on the rollers 348, the heel is simply pressed down. As a result, the buttock structural part 330 is pivoted about the pivot axis 352, the buttock 320 being simultaneously displaced backwards against the compression spring 329.1 of the functional unit to change the distance between the front and the rear sole holder, thereby enabling entry into the binding.

In summary, it can be stated that the invention provides a telemark ski binding, which on the one hand ensures good ski guidance even when the heel of the shoe is lifted off and on the other hand reduces the risk of injury to the skier in the event of a fall.
